To all whom it may concern:

Be it known that I, ALBERT DAY, residing at 10 Newport Gardens, Headingley, Leeds, in the county of York, England, have invented new and useful Improvements in or. Relating to Burners Applicable for Use with Incandescent Mantles for Gas-Lighting, of which the following is a specification.

This invention has reference to improvements in inverted mantles and burners employed for incandescent gas lighting.

Hitherto the nozzle portions of incandescent gas burners of an inverted lamp have been provided with one or more sets of projections arranged one above the other for receiving and supporting mantles of different kinds or sizes, the said projections being arranged near to the upper portion of the nozzle. In this invention the projections or flanges are provided respectively on the nozzle and the suspension ring of the mantle for an entirely diflerent purpose, and only one mantle is used.

The object of this invention is to prevent the unnecessary escape of ignited gas and products of combustion at the top of the mantle, and for confining the same as much as possible within its interior, and utilizing the said gas and products of combustion for increasing the incandescence and illuminating power of the mantle; at the same time reducing the consumption of the gas.

According to this invention the main portion of the inverted mantle is of the usual construction and material, except that the nozzle of the burner, and also the ring at the top of the mantle,hereinafter termed the suspension ring,by which the mantle is suspended from or by the nozzle of the burner are provided with a number of proj ections with spaces between the same, in addition to the ordinary supporting lugs. That is to say, the nozzle and the suspension ring are each provided with one or more rings of horizontal projections at right angles to the axis ofthe nozzle or the suspension ring, or with flanges having a number of recesses formed therein. In the case of the nozzle the said projections or recessed flange or flanges is or are on the outside of the same, and at a suitable distance from the lower end of the nozzle, but in the case of the suspension ring the said projections or recessed flange or flanges is or are arranged to project inwardly toward the nozzle and they are arranged at or near the lower edge of the suspension ring.

The herein described nozzles and the said suspension rings each provided with the said recessed flanges may be used separately or in combination.

In the drawings hereunto annexed are shown methods for carrying the herein described invention into practice, in which Figure 1 is an elevation of an ordinary nozzle with this invention applied and with the position of the suspension ring and mantle shown in dotted lines;

Like parts in all the views are marked with similar letters of reference.

At Figs. 1 to 4: a is the tubular portion of a nozzle of ordinary construction provided with a projecting portion a and a screw thread I) at its top for connecting it to the usual and ordinary gas fitting. Other means of attachment may be employed. 0, c are the ordinary recessed projections or supporting lugs for receiving the suspension arms of the mantle ring. (Z is the usual central hole for the passage of the gas to the inside of the mantle.

At Figs. 5 to 8 which illustrate the Great zin nozzle, the only diiference between that form of nozzle and those shown at Figs. 1 to l is that the tubular portion a of the nozzle is provided with an enlarged tapering head 6 in which are formed recesse f. The enlarged tapering head is placed immediately below the screw threaded portion 5 and it is also arranged to form supports for the suspension arms of the suspension ring. 9 is an ordinary suspension ring provided with the arms h which engage with the sets of recessed projections or lugs c, c.

All the above named parts are of the ordinary and well known construction and may be formed either of metal or of earthenware, or other refractory material as usual.

This invention consists in combining with the said nozzles and the mantle suspension rings a number of horizontal projections arranged in one or more rings with a space between the projections in each ring, or with one or more recessed flanges. The said projections or flanges form baflles for preventing the unnecessary escape of the gas from D the top or other portions of the mantle. In

the drawings the said projections or recessed flanges are marked with the reference letters 6 for the nozzles, and with j for the suspension rings, and the said projections, forming one or more recessed flanges, are in addition to the ordinary support projections or lugs 0, 0 and arms h.

In the case of the nozzle the projections i, which form a ring of baflies, are on the outside of the tubular portion a and they are arranged at a suitable distance from the lower end and orifice Z2 of the nozzle. In the drawings only one ring of projections or a recessed flange is shown, but it should be clearly understood that the number of these rings or flanges may be increased as circumstances require.

The number of projections z of each ring or flange correspond with the number of arms 72. on the suspension ring. That is to say, if three arms are provided,--as on mantle suspension rings of ordinary construction,then the flange 2' will be divided into three portions with a recess Z between each portion of the flange. The portions of the projections or flanges z are made smaller in diameter than the internal size of the mantle m so as to readily pass within the same and to leave a little space between their peripheries for the passage of the ignited gas and products of combustion. The main portions of the flange i are arranged to cover each opening or space n between the recessed projection c, and the recesses Z in the flange 2' will consequently be underneath the recessed projections 0. By this means both the flange i and the recessed projection 0 form baffles for the ascending ignited gas and products of combustion.

The hereinbefore mentioned projections z are formed at a suitable distance from the end of the nozzle in either one or more rings with openings or recesses between them. The spaces or recesses Z in each of the flanges or rings are made of such a size or width as to permit the suspension arms 1 to pass readily and freely between them. To place the suspension arms it on the re-' cessed projections 0 will require that space should not only be left in the recesses Z but also between each ring of projections so that the arms can be readily threaded and passed through the said spaces and recesses for placing them upon the recessed projection or lug 0.

In cross section the flanges or projections 2' are made of any suitable shape, such as, for example, flat, as shown.

The projections 71 are also made of such a thickness that they will readily become heated by the ignited gas within the mantle so as to form a kind of furnace therein for increasing the incandescence and the illuminating power of the mantle. The projections by forming baffles throw the ignited gas and products of combustion outwards towards the interior walls of the mantle and by impeding the flow of gases enable them to become more heated than with burners and nozzles of ordinary construction, and at the same time by reducing the space for their passage within the mantle they are brought into greater contact with the inner surface thereof thereby increasing the incandescence and illuminating power of the mantle with a. decreased consumption of gas.

At Figs. 10 to 15 the ordinary suspension ring is made either of metal or of a similar refractory material to that used for the ordinary rings of 'mantles and the nozzles of their burners. In this arrangement each suspension ring is provided with the ordinary suspension arms h-on its upper portion and also with the usual circumferential groove 0 for aiding in attaching the upper portion. of the mantle m, to the said ring. Instead of making the internal portion,' that is, the inner periphery,of the suspension ring with the usual vertical plain surface it is provided with a number of horizontal projections j arranged on the lower edge p of the ring 9. The projections j form an internal recessed flange. When projections j only are employed then there is a space 9 between each projection which takes the place of the recesses in the said flange. The internal diameter of the flange or projections is of such a size that the end of the nozzle of the burner, or the additional projections 73 thereon, can be made smaller in size and the sizes of the recesses 9 increased so as to permit of the said projections passing freely through the same.

The spaces 9 between the internal projections of the suspension ring g, provide for the upward flow and escape of the ignited gas and products of combustion, while the undersurfaces of the said projections, or of the internal flange, not only impede such flow, but also confine the said gas and products of combustion as much as possible'within the interior of the mantle thereby causing them to impinge upon its interior surface for increasing its incandescence and illuminating power.

Mantles provided with suspension rings arranged and constructed as herein described may be used with nozzles of burners of any ordinary construction or with nozzles having,in addition to the ordinary supporting lugs,one or more outwardly projecting recessed flanges or projections having a number of recesses or spaces in or between them for the ascending flow of ignited gas and products of combustion and for the passage of the ordinary suspension projections on the ring of the mantle.

What I claim is 1. In burners for incandescent gaslighting, a burner nozzle having supporting lugs on its periphery and a plurality of angularly spaced projections, and a mantle suspension ring having arms adapted to engage with said lugs and a plurality of angularly spaced projections on its inner periphery, substantially as set forth.

2. The combination with the burner nozzle and with the suspension ring used with incandescent mantles, of supporting lugs on the burner nozzle, arms on the suspension ring adapted to engage with said lugs, a plurality of projecting recessed flanges on the outer periphery of the said burner, and

also on the inner periphery of the suspension ring, the recesses in the said flanges being arranged below and under the said lugs and arms, and with the solid parts of one flange covering the recesses in another flange as set forth.

3. The combination, in the burner portion for an incandescent mantle, of the tubular portion of the burner having projecting lugs for receiving the arms of the mantle supporting ring with a ring of projections on its outer periphery formed at a suitable distance from its lower end, a recess between each projection, said recesses being arranged under the said lugs as set forth.

4:. The combination with a suspension ring for incandescent mantles having horizontal projecting suspension arms with a horizontal inwardly projecting flange provided with a plurality of recesses, said recesses being arranged under the projecting suspension arms, said recessed projecting flange being arranged on the lower edge of the ring, as set forth.

5. The combination of the tubular portion of an incandescent burner having a plurality of horizontal projections formed in a ring on its outer periphery at a suitable distance from its lower end, lugs projecting outward at its upper'end for supporting the ring to which the mantle is fixed, a space between each horizontal projection arranged below and under said lugs, a suspension ring for the mantle and having a plurality of horizontal arms at its top adapted to engage with the lugs of the burner, said suspension ring having internal vertical walls, an incandescent mantle and means for attaching it to the suspension ring, as and for the purposes set forth.

ALBERT DAY.
